This invention relates to improvements in.

winding machines for winding cops, cones, and similar forms of packages of thread,

yarn, cord and'other strand material, and parformation of bands or ribbons by the crowding together or piling of the coils.

As is well known to those versed in the art of winding, in drum-driven winders the speed of rotation of the packagediminishes with its increase in diameter during the progress of the winding and this causes a change in the ratio between the angular. velocity of the package and the rate of traverse of the yarn back and forth along its length. In conse-.

quence of this the character of the winding on the surface of the package is constantly changing. The turns of yarn may be spaced relatively far apart at the start of the package, but as the speed of rotation of the latter decreases the yarn coils will be laid closer together until they crowd and pile. As. the winding proceeds the coils are disposed farther apart again and this closing and opening of the wind repeats at intervals.

I A package in which the ribbon wind is prevalent is defective in that the yarn is stretched and strained .as the coils crowd together and pile and, furthermore, the yarn will not deliver freely therefrom under uniform tension. It has therefore been the practice to apply ribbon-breakers to drum-winders, such' devices operating to' disrupt the synchrony between the rotation of the package and the traverse of the yarn whereby to revent crowding or piling of the coils and defective winding.

He retofore in ribbon-breakers embodied in winding machines for preventing piling or crowding of the coils, speed-changing mechamsms have usually been employed for alternately lncreasing and diminishing the speed of one of the winding elements, either the packagesupport or the traversing-means which deposits the yarn in place on the package. Such mechanisms require a complication of gearing, cams, crank-motions and the like, and it is a principal object of the present invention to provide a ribbon-breaking de v 1ce of simpler construction with the elimination of gearing, coned pulleys, belt-shifting means and like apparatus. i

To accomplish the above-stated object the present invention contemplates the provision of means for periodically altering the position of the package in its contact on the drivling-drum whereby to vary thespeed of rota tion of the package to disrupt its synchrony.

with. the traverse of the yarn.

Another object of the invention is to prov de a mechanism of the type specified which acts to eriodically oscillate or tilt the package wit respect to the surface of the driving-drum, whereby first one end and then the other end thereof is engaged with the drum to alternately accelerate and decelerate the speed of rotation of the package.

Another object of the invention is to provide means of the type specified for effecting what may be termed a hee'l-and-toe action of a cone package on the driving-drum; that is, a rocking motion of the cone to cause it to engage the driving-drum first with its larger end and then with its smaller end to vary the speed of rotation of the cone.

Another object of the invention is to provide a mechanism of the type specified adapted 'to be operated from the builder-motion of the winding machine which determines theultimate form of the cone by gradually increasing the inclination of its axis to the periphery of the driving-drum to increase the taper on its surface.

Another object of the invention is to provide a mechanism of the type specified which may be applied to winding machines of 100 standard design without material alteration in the structure or arrangement thereof.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings.

In the drawings:

The present improved ribbon-breaker is adapted for use with practically all types of drum-driven winding machines but I have preferred to illustrate herein, by way of example, a standard type of winder as next described. Referring to Figs. 1 and 2 of the drawings, the gang winding machine herein shown comprises a horizontal bed or table 2 supported from legs or standards 3 and mounting a series of cross frames 4. The

several winding units, any number of which may be provided, are arranged along the opposite sides of the bed 2 with their mechanisms supported from the cross frames 4.

As all of the winding units are'of the same construction it has been considered suflicient to illustrate and describeonly one of them.

Opposite horizontal driving-shafts extend along the sides of the bed 2, beingournaled in suitable bearings 6 at the outer end of the cross frames 4, only one of these shafts being herein illustrated. The shaft 5 carries the drums or drive-rolls for the series of winding units on' one side of the machine, each drum 7 being secured fast on the shaft between a pair of the journals 6. The two parallel drum-shafts 5 may be. driven from any suitable source of power suchas an elec- 6 tric motor coupled to the shafts at the end of the frame, these connectionsnot being herein shown and described as they areof usualarrangement.

In the present type .ofwinding" machine the drum or drive-roll 7 also constitutes the traversing-means for disposing the yarn in helical coils extending from end to end of the package and crossing each other at intervals the yarn is received and guided ontothe.

package being wound. The groove 10 is continuous, extending from end to end of the roll in opposite directions. Means are vided at the points where the opposite he ices of the groove cross each other to maintain the yarn in that portion of the groove in which it is traveling and prevent it from being diverted into another portion of the groove to reverse its direction of traverse, all as fully set forth in the patent above referred to.

The winding machine 'as herein shown is adapted for winding frusto-conically shaped packages, commonly called cones. The cone C is rotatively supported to adapt its surface to contact with the periphery of thedrum or ro- V which the cone is wound, with the holder mounted on a swinging arm 12. As herein illustrated the cone-holder 11 is journaled on a spindle 15 which is swiveled in the forked end of a member 16 forming an extension of a rod 18. Referring to Fig. 4, the spindle 15 has a squared butt-end 19 pivoted on a pin 20 extending through the sides of the. fork 21, whereby the cone-holder 11 may be swung outwardly for convenience in applying the cone-tube thereto and dofiing or removing the completed package therefrom. A flat spring 22, secured to the side of the extension or member 16, has its end formed with a V- shaped detent adapted to snap into a similarly shaped notch in the end of the butt of the spindle 15 to normally maintainthe latter in parallel relationto the axis of the drive roll or drum 7. v

The rod 18 constitutes the main element of the supporting arm 12 for the cop-holder 11,

being mounted for rotation in a bearing 23 to I adapt it to swivel so that the axis of the cone 'may be tilted or inclined with respect to the. 1

surface of the driving-drum 7. The bearing 23 is formed as a part of an arm 25 which is pivoted on a stud 26 fixedly held in a hub 27 supported from one of the cross members 4 of the machine frame. hand in Fig. 2, the hub 27 is supported at the top of an upright arm or extension 28 on the 'bracket 4 and the stud or rod 26 is held fast As shown at the leftc the outer ayers of the cone.

' extension or tailpiece 36 which acts to limit- The arm 25 has a hub pivoted on the rod 26 abutting the side of the hub 27. The arm 25 is extended laterally in a'yoke 31 carrying a hub 32 at its outer end which also pivots on the rod 26. A collar 33 is secured to the rod 26 by a set-screw 34, and between the collar and the hub 30 of the arm 25 is a crimped or fluted spring-plate or washer 35 which acts to resiliently hold the hub 30 against the stationary hub 27. Through this arrangement the arm 25 is adapted to pivot on the rod 26 with a' slight frictional resistance applied to;

its movement as the cone-holder 11 is raised away from the driving-drum 7 during the growth in diameter of the package being wound.

The arm 25 has a downwardly projecting its swinging movement. Fixedly mounted on the top of the cross frame 4 is a member 37. A set-screw 38 passing through the side of the member 37 engages against the edge of the upright arm 28 to clamp the member 37 to the cross frame 4. The member 37 has an upwardly extending arm 39 through which projects a set-screw 40 adapted to make contact with the end of the tailpiece 36 on the arm 25 to limit the swinging movement of the, arm in one direction as the copholder is lowered towards the driving-drum or roll 7. The end of the tailpiece 36 is also adapted tostrike against a raisedledge or finger 41 on the opposite side of the member 37 to. limit the swinging movement of the arm 25 in the opposite direction when the cone-holder is raised away from the driveroll 7; the extreme position of the tailpiece lines in Fig. 1 of the drawings.

The rod 18 whichforms'the main arm or support for the cone-holder 11 is held in its bearing 23 on the arm 25 by meansof a collar 42 secured to the rod by a set-screw 43. The

collar 42 abuts one end of the hub or bearing 23 to take the end thrust of the rod in one direction and at the'opposite end 'of the hearing an arm 45 has its hub 46 clamped to the rod 18 by a binder-screw 47 to take the end thrust in the opposite direction. The'arm 45 constitutes one element of the builder-motion of the winding machine which acts to tilt the cone-holder to vary the inclination of its axis with respectto'the surface of the drive-roll during the winding, whereby to control or regulate the'degree. of taper on thesurface of the cone being wound. As'is well known to those versed in-the. winding art it is desirable that thecone be wound with agraduallyincreasing taper on its surface creasing the taper of the cone, and in the machine herein illustrated this mechanism is constructed and arranged in accordance with the invention disclosed in United States Let- I ters Patent No. 1,658,400, granted to E. B. Swanson, February 7, 1928. The coneholder 11 is rocked by the arm 45 previously described, the end of the arm carrying a follower 48 adapted to travel in an inclinedgroove or double-sided trackway 49 in a cam 50, shown in perspective view in Fig. 5. The grooved cam.50 is of arcuate shape, arranged concentric to the axis 011 which the coneholder arm 12 swings, and in the device of the patent previously referred to the cam is held fixed with respect to the cone-holder arm. With the arrangement as above described it will be observed that as the cone-holder 11 rises away from the drive-roll 7 with the growth in the winding the follower 48, traveling in the inclined groove 49 of the cam 50, will cause the arm 45 torock the cone-holder arm 12 with the rod 18 turning in its bearing at the base-end of the cone so that the taper.

on its surface will be gradually increased, this method of operation being well known to those versed in the present art.

In the present invention, as a simple and direct means for effecting-a continuous tilt lngaction of the cone-holder with respect to the drive-roll whereby to periodicallyalter the contact of the cone thereon to vary its speed of rotation, I make use of the elements 45 and 50 of the builder-motion in a manner as next described. Instead of mounting the cam '50stationary, as in the prior construction referred to, I pivot the cam on the rod 26 whereby it may be given an up and down oscillating movement in the manner and fo the purpose as later explained. a

ios

As best shown in Fig. 5 of the drawings,

the cam 50 is formed as a the rod 26. Fa'stened to the side of the arm 51 is a yoke 52 having a hub 53 ivoted on the rod 26 abutting the side of a xed collar 54 which, with the hub 27 on the upward extension of the frame member 4, takes the lateral thrust of the yoke, see Fig. 5. Referring to, Fig. 1, the yoke 52 has an elbow- 56 engage the periphery of an eccentric 57 carried on a rotating shaft 58, the eccentric being fastened to the shaft by means of a suitable set-screw 59. The shaft 58extends through bearings 60 depending from the artof an arm 51' which 1s pivoted to the right-hand end of cross members 4 of the machine frame, being rotated at a relatively slow rate of speed-to cause the eccentric 57 to rock the arm 55.

The shaft 60 ma shaft 5. or direct y from the power-applying means through any suitable connections not herein shown. I

It will be apparent that as the eccentric 57 is slowly rotated the arm 55 will be given a limited oscillating movement to rock the cam-track 50 up and down on its pivot. The rocking action of the cam 50 imparts a slight oscillatory movement to the arm 45, and thereby the rod 18 carrying themember 16 is rocked to oscillate the cone-holder 11 with respect to the driving drum. This method of operation of the device and itsresultin effect on the cone being wound is explained in connection with the winding operation as follows 1 The machine is prepared-for winding by placing a cop-tube or other package-support on the rotatable holder 11, the spindle 15 being swung outwardl on its pivot on the arm 12 while the latter is raised away from the drive-roll to facilitate this operation. After the cop-tube w has been placed on the holder 11 in this manner the spindle 15 is swung back to engage the V-shaped portion of the spring 22 with the notch in the end of the spindle to hold the latter in operative position. The yarn y is drawn from its source of supply, usually arranged below, led through a tension-device as generally provided, but not herein shown, and the end ofthe strand attached to the tube a: in any suitable manner. The surface of the cop-tube w is then placed in contact with the drive-roll or drum 7 by swinging the arm 12 downwardly and through this engagement the tube and its holder will be rotated from the drum.

As the yarn 3 leads from the tensiondevice to the tube a it draws across the surface of-the drum or drive-r0117 and the rotation of the latter willcause the strand to be picked up in the groove 10 on the surface of the roll to traverse it back and forth on the cop-tube in the usual manner. As the yarn.

50 is fed to the rotating cop-tube w and traversed back and forth thereon in an axial direction it will .be laid in a series of helical turns or convolutions which build up courses or layers of crossing coils. As the courses of winding are deposited in overlying relationship on the tube m the winding increases in diameter and thereby the cone-holder 11 is caused to recede from the surface of the drum or roll 7 with the arm 12 swinging upwardly on its pivot on the rod 26. As the copholder arm 12 moves upwardly in this manner the inclined cam 50 operates on the follower 48 to rock the arm in a contraclockwise direction as viewed in Figs. 2 and 3 of the drawings. This rocking motion of the be driven from the drum arm 45 turns the rod 18 in'its bearing 23 whereby to tilt the cone-holder 11 to incline its axis at an increasing angle with respect to the surface of the drive-r0117. The gradual tilting of the cone-holder causes the package to be built with. a progressively intion to the pack-age being wound. That is to say, as the follower 48 makes its gradual rise in the inclined slot 49 of the cam 50 the cam is given an up and down oscillating movement as imparted to it by action of the arm oscillated from the eccentric 57. This intermittent up and down rocking motion of the cam 50 causes the follower 48 to slide in the cam-groove to impart a relatively slow oscillatory motion to the rod 18 in'its bearing 23 and thereby its end-member 16 is rocked on an axis crossing the axis of the drive-roll 7. The eifectof this rocking or oscillating motion of the member 16 is to rock the cone-holder 11 to lift first one end and then the other end of the cone away from the drive-roll 7.

Stated briefly, the package being wound is rocked or oscillated to cause first one end and then the other to be released from contact with the surface of the drum or drive-roll 7 with a sort of heel-and-toe motion. In this manner the cone or package is engaged periodically with the driving-drum or roll 7 first at its larger end and then at its smaller end, and due to the disparity in the diameter of the cone at its opposite ends the result is that p the speed of rotation of the package is constantly varied. In other words, with the larger end of the cone engaging the drum as illustrated in Fig. 2 the package will be rotated at a slower rate of speed than when the smaller end of the cone is in contact with the drum as shown in Fig. 3.

The eriodic shifting of the engaging point of the cone with the roll between its extremes of diameter continues throughout the winding operation and in this way the angular velocity or speed of rotation of-the package is varied to disrupt its synchrony with the traverse of the yarn as effected by the groove in the roll 7.

The disruption of the synchrony of motion between the package and the traversing- 3 means acts to break up the regularity of the Wind so that the coils of yarn are prevented from gradually crowding together and piling to-forln bands or ribbons on the surface of the package.

It is to be observed that the present improved ribbon-breaker operates on an entire- 1y new principle to vary the speed of rotation of the package being wound whereby to accomplish the desired result.- The operating mechanism of the device is extremely simple and compact and adds but a single moving part to the winding machine. The

eccentric .57 which rocks the arm 55 to' oscillate the cam 50 may be rotated from a going element of the base machine, that is, the longitudinal shaft which carries the huntercams employed in machines of the present type as a knock-oil for the stopping mecha-' nism of the winding units. Moreover, in its preferred form of construction as herein shown and described, the ribbon-breaker utilizes certain elements of the cone-builder mechanism so that its structure is further simplified and compacted within a minimum compass.

It is to be particularly noted that in the present improved ribbon-breaker the usual.
